" If people want to save £4 billion and half a million tonnes of carbon More than the ban on filament bulbs will achieve, then they should stop throwing their money and carbon, literally, down the pan. If water were to be delivered and taken away by ten tonne lorry, instead of invisibly through pipes, then for every HGV on the road today, we would need to add another FIVE. Yes the water companies are the largest single users of electricity in the UK. The carbon footprint of water is 0.969 KgCO2/m3 (Water UK 2008)."

60 of the 150 litres we each use a day go for WC flushing. For 150 years, for no other reason than 'we have always done it this way', we have 'Pressed and let go' flushing a full cistern every time, a complete waste of water. Fit the Interflush retrofit kit to the existing WC siphon, connect to the front handle and now you have control on the amount flushed. 'Press, hold down to flush, let go to stop', using only what is needed, wasting none at all, saving half the flushing water on average, 30 litres per person per day.

Combined potential UK savings from using siphon flushing only, i.e. not using valve flushing and then fitting the Interflush are: 1.6 billion tonnes of water or 23% of UK water resources, £4.1 billion for consumers, 2.1 billion KWh of electricity and 1,6 million tonnes of carbon emissions. Cost £10-£15 per kit, see a payback of weeks not years, "a no-brainer" he claims.
